Nikon AF-S DX 12-24mm grinding noise

Hi md4, be a AF-S DX .
SWM or circuit problems in lens.
You have to take it to Nikon service to solve

Nikon currently lists two 18-55 AF-S DX and two 55-200 AF-S DX lenses. One in each pair has vibration reduction, the other does not. The ones with VR in the name have it, otherwise it doesn't.

VR isn't exactly an option. If it wasn't built into the lens initially, you can't add it later. A lens either has it or it doesn't, though if a lens has VR it can be switched off.

Nikon guarantees 5 year warranty to original purchaser. If your camera functions with another AF-S lens, then the problem lies with the 18-200mm lens. The AF motor unit needs replacement. Nikon should be able to repair the lens under warranty.
Make a copy of your receipt and go Nikon website to start repair service.

Hi,
Sorry to hear about your lens. If you are able to autofocus and take pictures with any other lens, then it means that your problem lies with the kit lens. If you can take picture in manual mode, but not in autofocus mode, then the AF motor in the lens in not functioning. I had the same thing happen to my 50mm 1.4 lens.
Depending on your location, there are Nikon repair centers in Melville, NY and Torrance, CA.
Hope this helps,
Andrew

try switching on manual focus...

Send it in for service. If it was purchased in the USA and you sent in the Nikon extended service contract that comes free in every Nikon USA lens then you have a 5 year warranty that covers most parts and defects. The warranty does not cover abuse, dropping sand damage etc.

well i had the same issue and i just slammed it (carefully of course) on the desk and it started working.... does it still zoom or does it just click and grind? also try zooming in and turning the lens faster outward or the oppsite direction to see if you can jump it back into the correct place on the gears.... my best guess is that it got dropped or the kids sat on it... and it made the gears slip into a bad place....

you call the computer expert to your home and then tell him this thing. he will give you the full idea about it. from my side it is the camera body.

Hey Embroiteri,
I hate giving out bad news, but it sounds to me like your focusing motor is broken. I am of course going on the assumption you have the camera set to AF mode, and the lens still doesn't focus. In my experience with SLR lens is that if there are scratching or grinding noises when either focusing or zooming there is almost always something broken inside.

Sincerely,
Allan
Go Ahead. Use Us.

Autofocus function on the D40 only supports lenses with the
AF-S feature, which have an autofocus motor built into the lens,
instead of using an autofocus motor drive built into the camera.

The Tamron lens you have, does not have a built in motor and
the autofocus function relies on the motor drive in the camera.

It will not work with the D40 or D60, but it will work with other
Nikon digital SLRs, such as the D80. Need to get an AF-S
type lens or upgrade to different Nikon digital SLR. Unless
you do this, you will have to manually focus the Tamron lens.

All of the Nikon DX (for digital) series lenses are also AF-S
type, so they will work with the D40, which is designed as
an entry level digital SLR, therefore it is intended primarily
for use with DX lenses, which are typically sold in a kit with
the D40. Most common one is Nikkor 18-55mm DX AF-S.

Other Nikon AF-S lenses made for film cameras (FX type)
will also work with the D40, but these tend to be expensive
professional models. DX series lenses tend to be more
affordable. You might consider the 18-200mm DX AF-S
as an alternative to the Tamron, but these are not cheap.
